Most of the existing caprolactam production devices operate and produce cyclohexanone as a raw material, and an esterification method is the latest cyclohexanone production process at present. The process has high conversion rate, almost no three wastes and high economical efficiency. And meanwhile, compared with other production processes, the esterification method has lower energy consumption. And the byproducts of the process can be used for other chemical production, so that the added value of the product is increased, and the economical efficiency of the product is greatly improved.
The feeding of the top of the cyclohexanone reaction kettle is controlled by an angle valve, and the angle valve is generally of an abduction disc type structure; because the medium contains toxic substances, the valve adopts a corrugated pipe sealing structure. The medium contains high-hardness solid particles, which are easy to wash and damage the corrugated pipe, thereby causing toxic leakage and environmental pollution and personnel injury. And under the high-scouring working condition, the whole service life of the valve is greatly shortened. The valve is frequently replaced and maintained, so that the device cannot be operated continuously, the production capacity of the device is severely restricted, and large economic loss is caused for enterprises. Therefore, aiming at the current situation, it is not urgent to provide an angle valve capable of meeting the working condition requirements.
